Io all whom it may concern:

Be it known that we, 13A L.-ABE and Jnoon Ann, citizens of the United States, residin at Alaska, in the county'oi -Minerai tate of West Virginia, have invented new and useful Improvementsin Lock-Nuts,

of which the following is'a specification.

Thii invention relates to devices for looking nuts and bolts together in such a manner to prevent the nuts from working loose cur-lat the same time permitting the device to be unlocked or locked by the application or. removal of a wrench to or from the nut. I

- .The invention has for one of its objectsto im-proveand simplify the construction and operation of devices ofth'is character so as to be-jcornparatively easy and inexpensive to manufacture, composed of few parts, readily mani ulated, and effective in use.

A urther object of the invention is the provision of a nut lockin device com rising a nut pro'vided with a c iamber in W ich is mounted a spring-pressed locking member in the form of a lever, the said locking member having one extremity formed into a hooker tooth for engaging ina groove or recess of the bolt to which the nutis applied,;-While the opposite end of the locking member rojects out of the c hamber so that thQ'IOC ing' member can be released and held in inoperative position by the application of a wrench to the nut for screwing the latter on the bolt or' removing it therefrom.

I With these objects in view and others, as

will appear'as the description proceeds, the

invention comprises the various novel. features of construction andarrangement of parts which will be more" fully described" and set forth with ap ended hereto.

axle spindle that has its outer end threaded at 23in the usual manner for the reception or" the wheeletainin nut 3, there being one or more longitudinal y extending recesses or grooves e in the threaded portion 2 of the spindle for the purpose hereinafter to ap can The nut 3 is provided with an areuate cnann her 5 that has its end at 6 opening into the bore 7 of the nut, while the opposite end S is open at one side of the nut, the chamber being concentric with the bore of the nut in approximately a quadrant of a; circle. To

construct the chamberfi, the nut is preferably made-of two parts and 'the chamber is and the open side of the chamber is closed by a plate 10.which is secured to the part 9 by screws 1101 other suitable fastenings.

In the chamber 5 is a locking device 12 that preferably comprises a strip of stiii' metal 13 that is curved to be assembled in the chamber and has .oneend bent into a V-shaped hook ortooth 14 which projects through the opening 6 to engage an one of the grooves or notches 4 of the spind e. The strip 13 is of such a length that the end opposite from the hook 14 will extend out of the openin locking position, as shown in Fig. 8, and will be pushed entirely into the said opening when a wrench is appliedto the nut. The strip 13 is provided with an apertured. lug 16 that projects from; the convex side thereof and extends into a recess 17 in the eoncaved wall of the chamber 5,, and-through the aperture of the said lug extendsa pivot 18,

and hook 14:, is a leaf spring 19 that has its 9 outer end slightly curved and bearing in the corner 20 of the chamber 5, the said spring being constantly under a tension tending to hold the member 12 in-locking position, and at the same time permitting the member to swing to unlocking position when it is de sired to apply or remove the nut.

. The Hut locking device is adapted for other-uses than with wagon axles for oreventing the wheels from workin oil, and for the nr ose of illustrating anot er use, the nut 00 'ng device-is shown 'a plied to an ordinary; bolt. in Fig. 5;. In this figure, the

bolt 21 is provided'with one or morenotches 8 when the member 12 is in return to locking position; It will thus-be as to withdraw the hook portion 14into the chamber 5. The nut can then be screwed on or removed without the locking device interfering and as soon as the wrench is removed, the 10 ing device willswing on its pivot by reason of the tension of the spring 19 and thereby cause the hook 14 to seen that the nut can be readily applied or removed and the locking device is automatic in its action.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and of the method of o eration will be readily apparent' to those ski ed in the art to which the present invention appertains, and while I have described the prlnoiple of operation of the invention, together with the apparatus which I now consider tobe the best embodiment thereof, 'I desire to have it understood that the apparatus shown is merely illustrative and that such changes may be made when desired as are within the scope of the claims.

Having thus described the invention, what I claim is v 1. The combination of a threaded member provided with one or more depressions, a nut on the member having an arcuate chamber open at one end to communicate with the bore of the nut and 0 en at its opposite endin one of the sidesu acesof the nut, and a locking device in the-chamber, said device consisting of an" arcuate strip bent inwardly into a hook at one endand shaped to'move in and out through the inner opening of the chamber for engaging or disengaging the depressions of the said member and having its on composed of two parts, one part having a I chamber opening into the bore of. the nut at one end and atone side of the nut at the op- .posite end, 0ne. side' of the chamber being closed by the second part of the nut, and fasteningdevices for securing the parts of the chamber, said locking device comprising .a strip of metal having one end bent intoan inwardly extending'V-shaped hook arranged to (project through the opening at the inner en 0 1 nut together; and a locking device in the said the chamber forengaging in a depression of the said threaded member, and the opposite-end being bent outwardly to project out of the outer openend ofthe chamber to be engaged by a wrench,-' a'lug formed on the said-member at a point intermediate the ends thereof, a pivot engaging in an opening'in the lug for removabiyhoiding themember in the chamber and to per- Il'lii? movement thereof, and a leaf spring secured at one end to the member at a point intermediate the lug. and inner end and having its opposite end disposed adjacent the hook to engage the wall of thechamber for holding the member in looking position.

In' testimony whereof We aff x our signatures in presence of two witnesses.
